DESCRIPTION

The ISO3086T is an isolated differential line transceiver with integrated oscillator outputs that provide the primary

voltage for an isolation transformer. The device is a full-duplex differential line transceiver for RS-485 and

RS-422 applications that can easily be configured for half-duplex operation by connecting pin 11 to pin 14, and

pin 12 to pin 13.

These devices are ideal for long transmission lines since the ground loop is broken to allow for a much larger

common-mode voltage range. The symmetrical isolation barrier of the device is tested to provide 3000 V

RMS

4242 V

of isolation for 1 minute per VDE between the bus-line transceiver and the logic-level interface.

Any cabled I/O can be subjected to electrical noise transients from various sources. These noise transients can

cause damage to the transceiver and/or near-by sensitive circuitry if they are of sufficient magnitude and

duration. These isolated devices can significantly increase protection and reduce the risk of damage to

expensive control circuits.

The ISO3086T is specified for use from –40°C to 85°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
